  • Partnerships target SF6 emissions - POWERGrid International

    Oct 01, 2000Since April 1998, the U.S. Environmental Protection Agency (EPA) has worked with the utility industry to voluntarily reduce emissions of sulfur hexafluoride (SF6), which is used as an insulating medium in electric equipment. As of Aug. 1, 2000, the SF6 Emissions Reduction Partnership for Electric Power Systems had 60 partners representing roughly 35 percent of U.S. net generating capacity.
